Added third brake light.

Some fleet vehicles have headlights on all the time the vehicle is on, so I would think it is fine to have lights constantly on.

Farmboy--be prepared that you may need to (re-)install two more marker lights so you have three in the middle, particularly if you have vehicle safety inspections. DOT standards call for the set of three, with a separation of six inches to a foot between each of the center ones.

I could easily do that, the side holes are plugged and wires are still there, I just couldn't fit the LED between them where they were mounted.

I like this idea!

I would also like to have tail lights on when driving in poor visibility from fog or snow. Ideally every vehicle would have tail lights on when the front driving lights (required in Canada) are on so drivers can see vehicles behind. Isn’t it just as important to see what is in front of you? We are constantly advised to turn on the full headlights in poor visibility “so the tail lights go on too.”

Anyone know if this would be a legal mod for the owner to do?

There are two outside edge lights I left alone. The bar lights a one running light and the third brake light when braking. The screw holes are siliconed and the Kerf is actually magic marker.

So does this LED bar light up three individual lights for the running lights and all the way across for brakes? Does it have a DOT approval number? I would not have thought it was accepted to have the space between the clearance lights lit up (even when braking), but I'm certainly no expert on vehicle lighting standards.

At any rate, it's an interesting sounding unit. I would suggest sealing the screw holes (and what looks like a saw kerf) where the old lights used to be as soon as possible lest you have water getting in and wrecking havoc.

Looks good. Will make you more safe.
